Hi, <br>You could try using the custom source streamtracer and use the plane as the input. That will release streamlines form all the points in the plane. <br>If this is not what you want you can calculate points on your plane using the normal vector coordinates and the center coordinates... <br>

Hello,<br>I would like to slice a 3D dataset with vector data attached to points but I would like to keep only the tangential part of the vectors, so as to compute streamlines lying on the plane then. If I use the slice tool, I can extract a place but with 3D vectors, which means that if I compute streamlines I get nothing because the is-in-domain test make the integration stooping immediatly (at least I suppose this is the reason). So I need to create a 2D vector field from a 3D one. Any advice?<br>
